Instran Nitrate Ion Online Concentration Meter (Colorimetric Method)
High absorbance can be obtained, allowing for high-precision measurements even at low concentrations.
Nitrate ions (NO₃⁻) are reduced to nitrite ions (NO₂⁻) under alkaline conditions. The resulting nitrite ions are then measured through a diazotization reaction. This reaction produces a vivid azo dye, and the intensity of the color is proportional to the concentration of nitrate ions. It should be noted that this measurement method assumes that there are no nitrite ions originally present in the sample.
